The world's largest burger chain announced more depressing results on Wednesday for the first three months of 2015.

The company vows a turnaround plan is coming. It will reveal the "initial details" on May 4. In a preview of what might be coming, McDonald's just announced that it's closing 350 struggling restaurants, mostly in Japan, the U.S. and China.

Just how bad is it at McDonald's? First-quarter profitstumbled by nearly $400 million, or roughly a third. That's a steeper pace of profit declines than all of last year.

No wonder McDonald's changed its CEO in late January. As if the burger chain didn't have enough to deal with, it's getting hit by the strong U.S. dollar. All those foreign restaurants aren't helping the bottom line since the company is taking a hit on currency exchange.

The good news for McDonald's is that investor expectations are low at this point. The stock is actually jumping over 2% Wednesday as investors are hopeful that new CEO Steve Easterbrook gets it and will bring a strong plan. They are also happy that total sales didn't fall by more than feared.

McDonald's is now testing all-day sales of breakfast items, selling sirloin burgers and perhaps even kale eventually, at least according to one analyst.

It's also cutting back on restaurants that aren't adding to the company's profits. The 350 store closures announced on Wednesday are in addition to the 350 the company had already planned on shuttering this year.

But don't expect the negative trends to change just yet. McDonald's warned that its global sales are likely to fall in April as well.
